Formation

In prehistoric times the bay was land. As sea levels rose, erosion shaped the coastal landscape over millions of years. Several blocks of granite or granulite emerged in the bay, having resisted the wear and tear of the ocean better than the surrounding rocks. These included Lillemer, the Mont-Dol, Tombelaine (the island just to the north), and Mont Tombe, later called Mont-Saint-Michel.

Mont Saint-Michel was previously connected to the mainland via a thin natural land bridge, which before modernization was covered at high tide and revealed at low tide. This connection has been compromised by several developments. Over the centuries, the coastal flats have been polderised to create pasture. Thus the distance between the shore and the south coast of Mont-Saint-Michel has decreased. The Couesnon River has been canalised, reducing the flow of water and thereby encouraging a silting-up of the bay. In 1879, the land bridge was fortified into a true causeway. This prevented the tide from scouring the silt around the mount.

On 16 June 2006, the French prime minister and regional authorities announced a €164 million project (Projet Mont-Saint-Michel) to build a hydraulicdam using the waters of the river Couesnon and of tides to help remove the accumulated silt deposited by the rising tides, and to make Mont-Saint-Michel an island again. It was projected to be completed by 2012.

The construction of the dam began in 2009 and is now complete. The project also included the destruction of the causeway that had been built on top of the small land bridge and enlarged to join the island to the continent, and was used also as a parking lot for visitors. It will be replaced by an elevated light bridge, under which the waters will flow more freely, and that will improve the efficiency of the now operational dam, and the construction of another parking lot on the mainland. Visitors will use small shuttles to cross the future bridge which will still be open to pedestrians and unmotorized cycles.

France is affectionately referred to as "the Hexagon" for its overall shape.French history goes back to the Gauls, a Celtic tribe which inhabited the area circa 300BC until being conquered by Julius Caesar.The Franks were the first tribe to adopt Catholic Christianity after the Roman Empire collapsed. France became an independent location in the Treaty of Verdun in (843 AD), which divided up Charlemagne's Carolingian Empire into several portions.The French monarchy reached its zenith during the reign of Louis XIV, the Sun King, who stood for seventy-two years as the Monarch of all Monarchs. His palace of Versailles and its Hall of Mirrors are a splendid treasure-trove of Baroque art.The French Revolution ended the rule of the monarchy with the motto "Liberty, Equality, Fraternity!" On July 14th, 1789 angry mobs stormed La Bastille prison and began the Revolution in which Louis XVI, his wife Marie-Antoinette and thousands of others met the guillotine.One decade after the revolution, Napolean Bonaparte seized control of the Republic and named himself Emperor. His armies conquered most of Europe and his Napoleonic Code became a lasting legal foundation for concepts of personal status and property.During the period of colonization France controlled the largest empire in the world, second only to Britain.France is one of the founding members of the European Union and the United Nations, as well as one of the nuclear armed nations of the world.Text by Steve Smith.
